Answer:
-30
Step-by-step explanation:
y = -10x is a function that can also be represented by f(x) = -10x. We are to evaluate this function at x = 3. To do this, replace both instances of x in this function by 3 and simplify the result:
f(3) = -10(3) = -30
y= -30
THis is because you substitue 3 for X and then multiply -10 and 3 and a negative times a positive is a negative so -10 times 3 is -30
tr it and it wil; he;p
y-6=4(x+3)
-30+10b=-22
32-22=10b
10b=10
-32+10=-22
hope it helps
